<p>总体介绍互联网传输的的protocols<br>IP 协议与 IP module 有所区别, IP 协议只是 IP module 中协议的一种, tcp/ip 指的是只是module, 代表当前最通用的传输协议实现方案</p>
</blockquote>
<ol>
<li>IP</li>
</ol>
<ul>
<li>ip addressing<ul>
<li>五类IP地址, IP编址, 不能满足全世界的人, 采用子网掩码功能(Subnet)</li>
<li>网络地址 主机地址</li>
<li>那么多的主机, 都通过一个端口, 能处理的过来吗?<br>  对于外网的ip 是给服务器用的, 虽然ip是共用, 但是能力还是服务器的, 所以处理能力跟服务器有关, 但是同一时间同时访问, 确是对应一条网络, 如果有大量的数据请求, 就是dos攻击的形式了, 所以上限还是线缆的传输容量</li>
<li>NAT, Network Address Translation, 网络地址转换技术, 子网掩码是理论, NAT是实现</li>
</ul>
</li>
<li>ip subnet<ul>
<li>知道了子网的掩码的作用, 关键是需要实际操作</li>
<li>子网掩码是为了解决互联网爆炸似的成长, ip不够用的情况</li>
<li>To avoid having to request additional IP network address, </li>
<li>其实对于子网掩码还是疑惑着呢? <blockquote>
<p>子网掩码到底能不能解决 ip 不够的问题呢?<br>看了半天, 子网掩码, 貌似只是将网络本来的ip分得更细了,  A, B, C, D 类网络的 ip总地址并没有增加<br>解决ip枯竭的思想是多台主机共用一个ip, 这个主要也是靠 NAT 程序?<br>再看了一遍, 更不明白了,  subnet 只是与 remote net 保持同样的形式, 可以根据 local net 的规模来确定 net 与 host 的长度, 但是 net 的长度没有用, 主要是用host的长度, 这样再配合NAT程序, 也能达到扩展网络ip的功能, The entire network still appears as one IP network to the outside world.</p>
</blockquote>
</li>
<li>multihomed hosts, network adapter<br>  A multihomed host has different IP address associated with each network adapter.<br>  Each adapter connects to a different subnet or network.</li>
</ul>
</li>
<li>IP routing<ul>
<li>gateway: a system that performs the duties of router.</li>
<li>direct, indirect: ascribe physical network</li>
<li>A router is needed to forward traffic between subnets.<br>  so, if I want the outnet device to access the subnet device, also work by the router.</li>
<li>ip routing table <ul>
<li>The ditermination of direct routes is derived from the list of local interfaces. eg. hosts </li>
<li>Each host keeps the set of mappings between in following:<blockquote>
<p>Destination ip network addresses<br>routes to next gateway </p>
</blockquote>
</li>
<li>Three types of mappings are in this table<blockquote>
<p>The direct routes discribing locally attached networks<br>The indirect routes describing networks reachable through one or more gateways.<br>The default route that contains (direct or indirect) route used when the destination ip network is not found in the mappings of the previous typs of type 1 or 2</p>
</blockquote>
</li>
</ul>
</li>
<li>ip routing algorithm<ul>
<li>a unique algorithm </li>
<li>to differentiate between subnets</li>
<li>not difficult for algorithm, difficult to read English</li>
</ul>
</li>
</ul>
</li>
<li>methods of delivery: unicast, broadcast, multicast, anycast<ul>
<li>refer name to know sense</li>
<li>A connectionless protocol can send unicast, broadcast, multicast, or anycast messages.</li>
<li>Brocast addcresses are never valid as a source address. They must specify the destination address.<br>  BOOTP can use broadcast addresses to allow a diskless workstation to contact a boot server.</li>
<li>It is not only way to the netbar,  the more senarios is talked in the next chapters.</li>
</ul>
</li>
<li>the ip address exhaustion problem<ul>
<li>The number of networks on the internet has been approximately doubling annually for a number of years.</li>
<li>I don`t understand how to solve this problem yet.</li>
<li>Class A,B,C,D network, only has 255<em>255</em>255*255 ip, these are less than 6 billion people, so there the subnet tecnology share one ip.<br>  every class network has limit subnets, this also is not the permanant solution.<br>  这样的话, A类网络会不会将线路爆<br>  ipv4 and ipv6</li>
</ul>
</li>
<li>Intranets: private ip address<ul>
<li>Another approach to conserve the IP address space.</li>
</ul>
</li>
<li>network address translation (NAT)<ul>
<li>read finished, but has no information, just know some terms, IPSec, NAPT</li>
<li>translate the ip and port, also to resolve the ip exhaustive </li>
<li>NAT limit</li>

</li>
<li>Classes Inter-Domain Routing (CIDR)<ul>
<li>also have no information, just reading once over</li>

<li>ICMP Router Discovery is a proposed standard protocol with a status of elective.</li>
</ul>
</li>
<li>ICMP can be characterized as follows:<ul>
<li>ICMP uses IP as though ICMP were a high-level protocol. However ICMP is an integral part of IP and must be characterized by every IP modules.</li>
<li>ICMP is used to report errors, not to make IP reliable.</li>

<h2 id="问题"><a href="#问题" class="headerlink" title="问题"></a>问题</h2><ul>
<li>写完上面的几个协议, 就解决了之前的疑问, IP 是属于网络层的<br>  这几个主要协议, 构成了网络层, 从名字, 也可知 网络层的功能</li>
<li>看前面 Network Interface 是有些枯燥, 到了这里, 可能才更有意思一些<br>  包括后面的 routing protocol, transprot layer protocol 都主要是了解这些协议的功能构成, 以及查看这些协议的工具, 有何用途, 能做何用</li>
<li>为何要看TCP/IP<br>  想弄明白网络中的那些事, 除了架个服务器, 让自己的电脑能被外网访问, 还能干些什么事? 为何会有这些协议,  路由器还有哪些高级的玩法, 如果管理自己的网络, 如何管理分布式网络, 如何配置自己的局域网络, 如何用网络, 将自己的生活圈子组建起来?<br>  了解一下SMTP, FTP, HTTP等协议, </li>
<li>tcp/ip 看完, 能否对 lantern 有所改动, 可以少点会员费, 还能使用优质网络?</li>
</ul>
<h2 id="思维重组"><a href="#思维重组" class="headerlink" title="思维重组"></a>思维重组</h2><ul>
<li>想从tcp/ip中了解一什么?</li>
<li>数据是如何从一台设备到另一台设备中?<br>  按协议来, 二进制对应着高低电平, 高低电平的意义用布尔逻辑来解释</li>
<li>其中的实现细节, 我需要了解到哪些?<br>  这些不清楚, 所以只能先通读, 有所也解后, 再按点突破</li>
<li>在linux能用到哪些?<ul>
<li>服务器编程<br>  翻墙<br>  邮件服务分发器<br>  局域网络<br>  路由的操作<br>  游戏服务器<br>  操作系统中的端口, 是真得有端口, 还所有数据从一个物理入口进入, 程序按端口来分发消息?</li>
<li>整个网络 基本上是就是数据的存储与搬运, 数据如此重要, 必然要考虑安全问题<br>  怎么去保证数据互通<br>  怎么拦截数据, 有哪些部分可以获取到数据<br>  跟数据相关的安全和攻击有哪些<br>  数据的加密, 有没有必要了解一番</li>
<li>黑客<br>  攻<br>  防</li>
</ul>
</li>
<li>从哪里入手<ul>
<li>书籍, 就是再枯燥, 也得通读一遍, 至少各个环节能自圆其说</li>
<li>读的过程中, 尽量再发散, 以英文作笔记, 抛开中文都写不好文章的恐惧, 重新学习写作, 从语言开始, 是一个好机会</li>
</ul>
</li>
<li>效率<ul>
<li>最快得效率, 还是要保持一定的套路, 思维套路来分析, 不然很容易就陷入迷茫, 不知在看些什么的窘境中</li>
<li>看一本书, 先从目录分析, 一本书太广, 就按目标计划来分析, 或一章章的分析</li>
<li>每章每小节, 按标题分析, 分析不到的, 就从是什么, 能解决什么, 应用场景来泛读</li>
<li>根据应用场景与兴趣, 再进一步精读是怎么做到的</li>
</ul>
</li>
</ul>
<h2 id="review"><a href="#review" class="headerlink" title="review"></a>review</h2><p>再次设置网络还是有些迷, 子网掩码如何设置? 两台电脑是如何通信的? 路由是如何转发数据的? 这些还是不明白. </p>
<p>设置一个路由, 使两个设备能通信, 还是现实中很重要的一个场影, 一旦可以找到目的电脑, 那么应用就可以用了. </p>
<p>两台主机直连, 点对点通信, 即在同一个IP局域网内或令牌环网内. 这个时候可以直接被本机的路由列表感知到? </p>
<p>现在主要是攻破, 不在同一个局域网内的通信, 路由如何选路, 数据如何到达目的地的. </p>
<pre><code>首先不要网线的转输能力不用置疑, 在一个子网下肯定可以满足. 

不管是主机还是路由都有路由表</code></pre><p>网络层, 是对通信过程的抽象. 每一个路由理论上是对每一层协议都要感知的. 每一层管每一层的事, 每一层大都不只一个协议实现.<br>这样想, 一下子就明了了, 关键还是要理解业务. </p>
